Hello to everyone in this forum. I'm thinking of purchasing a Y2K WR400 and I have the following query: I'm from Singapore and there are not many WR4 owners, it seems that XR4 is a more popular choice among Singaporeans, as it's easier to maintain. Is the WR4 easy to maintain, what are the main problems that WR4 owners face? Parts for WR4 is also not readily available here. Please give me your advice, thankz!!!
